1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. f3 {A popular move nowadays, but it was
Volkov, Yakovich and Moskalenko who brought it to the limelight} O-O 5. a3
Bxc3+ 6. bxc3 Ne8 {Franco employs a thematic maneuver, first introduced by
Capablanca, although it was in a slightly different version. The knight is
brought over to put pressure on c4, via d6, and at the same time the pin Bg5
is stopped (once White plays e4, Bg5 is very nasty). The downside to this move
is that it doesnґt pay much attention to development and gives White a very
broad pawn-center.} ({The main alternatives are} 6... Nh5 {, gaining a tempo (.
..Qh4 is a threat) to introduce the f-pawn into the fight for the center.}) ({
and} 6... d5 {, which is a much more classical approach.}) 7. a4 {A very
ingenious idea of Mamedyarov which I donґt think will become too popular
though. After ...Ne8 Black has made clear that he wants to play ...b6, ...Ba6,
...Nc6 and ...Na5. With a4-a5 White tries to hinder such a setup, while
getting rid of the potential weak a-pawn in the process. The problem is that
two tempi are spent doing this, tempi which could prove more useful by simply
developing.} ({Actually,} 7. e4 {has been enjoying pretty good results lately:}

of moves have been pretty standard. Now the c4-pawn cannot be taken due to
several tricks down the a-file: 12...Bxc4 fails to 13.Rxa5 Bxd3 14.Rxa8
followed by 15.Qxd3, while 12...Nxc4 is met by 13.Rxa6.} Rc8 $5 {A
funny-looking move, but one that causes trouble. Suddenly 13...Bxc4 turns out
to be a threat, since 14.Rxa5 Bxd3 no longer works because Whiteґs rook would
be hanging and there is no black rook to take on a8! Also, the rook on c8
could prove useful whenever Black plays ...c5.} 13. Qe2 Qh4+ ({Franco had a
more principled possibility here:} 13... c5 14. dxc5 ({is an obvious
alternative:} 14. d5 exd5 ({Black can also try} 14... e5 {, keeping the
position closed in order to attack c4 in peace.} 15. f4 (15. Nf2 $6 Nd6 16. Ng4

protect c4 and enjoy a great plus.} {But} Bxc4 17. Nxe5 Qf6 $1 {is a killer:}

prefer leaving Black with a passive Ba6.} Nxc1 16. Rxc1 Nd6 17. O-O (17. Ra1

manage to put some pressure on my opponent.} Rfb8 24. Nb5 Qd8 $6 (24... Qe7 {
